Two sisters defied the odds to BOTH gave birth to identical girl twins within weeks

Megan O'Brien, 29, gave birth to Lilah and Josie, and sister, Sara Seyler, 32, had Lennon and Parker just three months later.

The double pregnancies came as a shock to both women as twins do not run in the family at all.

Although Megan's husband, Matt is a triplet, there was no indication Megan would give birth to twins, never mind her sister Sarah too.
